I just love this.

Here's something that wouldn't have been possible before things like YouTube...

Kids do this sort of thing as their full-time job - mashing things together.

It's amazing how well these various clips go together - with a whole lot of editing of course. It's important not to forget how huge the role of the editing is here - editors make a video or movie into what it's going to be. So next time you see a show or movie you like, thank the editor.
